Device for suspending rings for gymnastic exercises

Abstract

A device for suspending gymnastic rings and handles is described. The device has a power spring to automatically retract a strap onto a spool. There is a cam buckle that holds the strap in place at a desired height. There are marks on the strap to use as reference to easily match the rings to the same height. The device is typically used as a pair, one device for each ring. Many handle and bars can be attached.

I claim: 
     
       1. A system for vertically suspending at least one hand grasped device from an elevated structure and allowing for variations in a height of the at least one hand grasped device, the at least one hand grasped device including an exercise ring, the system comprising:
 a device frame having an upper end defining a point of attachment for fixed suspension from the elevated structure; 
 a cam buckle supported by and positioned on a lower end of the device frame, the cam buckle having a pivot axle; 
 a spool having a rotation axle, the spool axially supported on the device frame at a position between the upper end and the lower end of the device frame; 
 a coil power spring fixed to the device frame, the coil power spring gearlessly and peripherally coupled to the spool; and 
 a strap wound onto the spool, the strap comprising indicia spaced at regular intervals to facilitate setting a plurality of the at least one hand grasped device to a same height, the strap extending from the spool towards the lower end of the device frame, the strap having a lower end extending from within the cam buckle to a point of attachment on the at least one hand grasped device; 
 wherein release of the cam buckle allows the strap to be drawn out from the spool or alternately retracted back onto the spool, wherein closure of the cam buckle prevents the strap from movement therethrough in at least a downward direction, and wherein the coil power spring serves to preference the retraction of the strap back onto the spool after being drawn out from the spool when the cam buckle is released. 
 
     
     
       2. The system of  claim 1  further comprising a length of linked chain secured at an upper end thereof to the elevated structure and extending downward to a lower end of the length of linked chain being fixed to the point of attachment on the device frame. 
     
     
       3. The system of  claim 1  wherein the cam buckle is spring loaded. 
     
     
       4. The system of  claim 1  wherein a downward force by the strap serves to tighten the cam buckle on the strap. 
     
     
       5. The system of  claim 1  wherein the coil power spring is coaxial with the spool and is positioned adjacent to the spool on the device frame.
